One Direction will attend their first awards show as a four-piece later this month.

The chart-topping band - featuring Niall Horan, Harry Styles, Liam Payne and Louis Tomlinson - have been confirmed as presenters for an award at the 2015 Billboard Music Awards on 17 May, which will be their first red carpet event since Zayn Malik left the band in March.

The 'Night Changes' singers - who are nominated for four awards including Top Artist and Top Duo/Group - will join other famous faces at the event including Laverne Cox, Celine Dion and Rita Ora, as well as hosts Ludacris and Chrissy Teigen.

The awards show, broadcast live from the MGM Grand Garden Arena in Las Vegas, will also include performances from Ed Sheeran, Nick Jonas and Kelly Clarkson, with Britney Spears and Iggy Azalea performing their new single 'Pretty Girls' for the first time.

However, following Louis' recent online spat with Zayn, Harry's relationship with Louis has reportedly become "strained".

A source told The Sun newspaper: "Harry is very aware of 1D's reputation and doesn't like getting into any public scrapes, especially with other members of the band.

"It's fair to say his relationship with Louis has been strained for some time and the last couple of weeks hasn't helped matters."
